I finished all the objectives in the tutorial, but at the top of my screen it says, "Cool! You have earned enough experience to Train your Minion. Click on the Train link in the Active Character section."

I assume the tutorial prompts will disappear after a while. The tutorial is a wonderful addition, but you can figure things out without it. I really think it's a nice way to keep people coming back, and if anything, I wish it could be continued to include more strategy tips.

lets just say that after you go through your tutorial usually the 1st thing you would do after is start a new character which hasnt been influenced by a poor tutorial which forces you into basically creating a team that you dont want

...Or we could just fix the tutorial itself. It has been bugged for a while now. Not to mention it does a poor job of explaining the game, while forcing you to hire when you don't want to.
Excuses are always brought up: "there are more important things to fix."
But, my argument is this: "There is nothing more important to a failing community than new members."

I suppose after you play a game for years and years you become a little dull to the fact that newbies don't want to waste their time paying outstanding amounts of money for minions they don't want; starting over doesn't sound too appealing either.

Way i look at it is you have a better understanding of the game then some already, and your to advanced for that part of the tutorial. So if you want to complete it you have to make the sacrafice. Instead of trying to milk it.
If it was originally designed to be milked then yeah fix it.
